Key traits:

• Always spelled whisky (no “e”).

• Must be aged at least 3 years in oak barrels.

Flavour profile:

• Can be smoky, earthy, malty, or fruity depending on the region (Islay = smoky, Speyside = sweet/fruity).

Sub‑types:

• Single Malt (one distillery, malted barley only)

• Blended Scotch (mix of malt + grain whiskies)

2. Irish Whiskey (Ireland)

Key traits:

• Usually spelled whiskey (with “e”).

• Typically triple‑distilled, making it smoother.
